There are many things in Kurotō Keiji's mind. Even if Tang Cheng has successfully copied three fifteen-second memory fragments from Kurotō Keiji's mind, it is impossible to copy everything. Tang Cheng, who had used up his share of the memory copying skills for the day, calmly released his left hand that had been holding the opponent's shoulder blade, and then asked a few more irrelevant questions before Shi Shiran left the interrogation room.
"How is it?" Zhang Jianghe was still studying the list. Seeing that Tang Cheng's expression did not seem to be troubled, he asked Tang Cheng with a little expectation. Tang Cheng did not answer Zhang Jianghe immediately, but first picked up the cigarette on the table and lit one, and then squinted and chuckled under Zhang Jianghe's expectant eyes. Zhang Jianghe was stunned for a moment when he saw this, and then he also laughed.
After getting along with Tang Cheng for almost a year, Zhang Jianghe had a certain understanding of Tang Cheng's character. Zhang Jianghe had seen this smile on Tang Cheng's face many times, and it was always after the operation was successful. For Zhang Jianghe, Tang Cheng's smile at this moment was a kind of affirmation, so he smiled accordingly. "It doesn't have to be that troublesome to unravel this list. This guy has something hidden somewhere else. As long as the two things are put together, the code format will be cracked."
What Tang Cheng said at this moment was naturally the memory fragments he copied from Kurotō Keiji's mind, and he already knew where Kurotō Keiji hid another thing. "Okay, this is great!" Zhang Jianghe couldn't help but feel overjoyed when he learned that Tang Cheng had a way to unlock the secret word list. Although he didn't know the contents of the secret word list yet, Zhang Jianghe knew that it belonged to him. A good opportunity.
Zhang Jianghe did not know the contents of the secret language list, but Tang Cheng had already learned from the copied memory fragments that the people on this list were all Japanese deep divers who began to secretly deploy into Sichuan after the September 18th Incident. . Nearly six years have passed since the September 18th Incident in 1931. The deep divers that the Japanese deployed into Sichuan six years ago should have lurked into all walks of life in Sichuan. These have adapted to the local environment. The lurkers in life, if they don't take the initiative to reveal their identities, they probably won't be noticed by anyone.
When he thought of this, Tang Cheng's brows had already furrowed slightly, because he knew that Kurotou Keiji was just one of the many deep divers who initiated the movement. There were less than 15 people on the list of deep divers in his hand. If there were still more people in Chongqing, For a deep dive starter like Kurotou Keiji, the consequences would be serious. At this moment, Tangcheng understood why Chongqing was continuously bombed by Japanese planes during the Anti-Japanese War. It was because there were so many traitors in Chongqing who worked for the Japanese. If they had not taken the initiative to provide ground guidance and relevant intelligence for Japanese planes, , why was Chongqing bombed so badly during the Anti-Japanese War?
But it was different now. Tang Cheng still had his family and relatives in the city, and he would never allow the tragedy to happen again. Although there is no way to prevent the bombing of Japanese aircraft, Tangcheng is definitely capable of eradicating the traitors and scum who provide ground guidance for the Japanese in the city. As long as there is no ground guidance, Chongqing, which is dubbed the Fog City, may not be able to stage the tragedy of its previous life. Even if he could save one more person, Tang Cheng would be willing to do so, not to mention that his family was also in this city.
Tang Cheng volunteered to find another item hidden by Kurotou Keiji, while Zhang Jianghe continued to stay in the military camp and waited for Tang Cheng's return. After about an hour, Tang Cheng left and returned, and Kuroteng Keiji hid elsewhere. The things have been obtained by him. "Is this a caliper?" Zhang Jianghe was confused by what Tang Cheng brought back, because what Tang Cheng brought out was clearly a vernier caliper commonly used by factory technicians. However, after Zhang Jianghe took it and looked at it carefully, he immediately Found something suspicious.
"This is what the target is hiding. I was thinking about it on the way back, and I found that the scale on this caliper is different from ordinary calipers." Zhang Jianghe's exclamation just now made Tang Cheng realize that Zhang Jianghe also noticed the difference in this caliper, so before Zhang Jianghe could speak, Tang Cheng pointed out the difference in this caliper.
"Not only are the scales different, but if you look carefully, the scales on this caliper are completely messy. Except for the scale numbers, which are marked step by step, even the two adjacent scales on it have different lengths." Tang Cheng continued. Pointing out the second difference of this caliper, Zhang Jiang and Wen Yan looked at it carefully. Sure enough, the scale on this caliper looked like a toy. Vernier calipers used in serious factories would never look like this. mistake.
"But what does this caliper have to do with the list? Is it possible to use this caliper to read the list of secret words?" Tang Cheng, who already knew how to use the caliper, pretended not to know anything at this time. , just by talking to himself, he revealed the truth to Zhang Jianghe bit by bit. Tang Cheng's soliloquy really reminded Zhang Jianghe, and he immediately leaned over the table with a caliper. After playing with it for a while, he still couldn't find the right method.
Tang Cheng saw it and was anxious in his heart, thinking that you, an old man, is missing an arm, how can you use a caliper and adjust the scale of the caliper at the same time. "By the way, before the target fainted, he was still mumbling 30 and pi. Uncle, do you think this has something to do with how to use this thing?" Zhang Jianghe's efforts were fruitless, so Tang Cheng had to borrow the Black Vine Sutra. Er's mouth revealed the secret to Zhang Jianghe.
"30 and pi?" Before joining the army, Zhang Jianghe had attended private school for several years. How could he know what pi was? With these two words in his mouth, Zhang Jianghe was already anxious. Tang Cheng had no choice but to secretly think about what kind of excuse he should use this time so that he could speak out again to remind Zhang Jianghe. Zhang Jianghe was lying on the table, looking at the list of secret words, fiddling with the caliper in his hand. However, he didn't know the correct way to use the caliper, so naturally he couldn't find any answer.
"Uncle, let me try it!" After a quarter of an hour, Tang Cheng, who finally couldn't bear it any longer, reached out and took the caliper from Zhang Jianghe's hand, imitating Zhang Jianghe's behavior just now, leaning over and looking at him in a pretentious manner. List of secret words on the table. "Uncle, I counted the words on this piece of paper. There are 450 words in total. There are no punctuation marks, and we don't know how to segment sentences. The target is 30 at the end. I think it's better to just copy these 450 words. For every 30 words, divide them into fifteen paragraphs."
As Tang Cheng spoke, he took the pen and paper and neatly copied the 450 words on the list of secret words on another piece of paper, with 30 words per line. Zhang Jianghe did not stop Tang Cheng, but Zhang Jianghe still couldn't understand the content that Tang Cheng had transcribed in sections, until Tang Cheng picked up the caliper again. “When I was in middle school, my school teacher used to teach me that pi is a mathematical constant that is ubiquitous in mathematics and physics.”
Zhang Jianghe was confused about the mathematical constants mentioned by Tang Cheng, but after Tang Cheng said that he probably still remembered part of pi, Zhang Jianghe finally became energetic. "This pi is actually the ratio of the circumference and diameter of a circle. It is an irrational number and has the property of infinite non-cyclicity." Tang Cheng had no way to explain to Zhang Jianghe what irrational numbers and the properties of infinite non-cyclicality are, because Zhang Jianghe had In private schools, these contents are not taught at all.
The most commonly used approximate value of pi is 3.14, and 3.141592654 to ten decimal places is sufficient for general calculations. However, this is not what Tang Cheng will tell Zhang Jianghe later. What he will tell Zhang Jianghe is the fifteen-digit pi. Looking at the fifteen Arabic numerals written by Tang Cheng at the bottom of the paper, Zhang Jianghe didn't understand how these numbers were related to the list of secret words.
Tang Cheng was too lazy to explain too much to Zhang Jianghe now. He just started to use the caliper based on the memory fragments he copied from Kurotou Jingji's mind. In the fifteen paragraphs of text he re-copied, he began to use the caliper to The characters corresponding to the scale numbers are marked one by one. Zhang Jianghe didn't understand the purpose of Tang Cheng's actions at first, but after Tang Cheng followed certain rules and used a caliper to mark the contents of the fifteen paragraphs one by one, he finally understood.
"No! You still can't understand what you marked with a caliper?" The words that Tang Cheng marked with a caliper were re-copied on new paper by Tang Cheng, but no matter what Tang Cheng used, fifteen characters per row Or the original thirty characters per row were rearranged, and the final read content seemed to be completely inaccurate. Zhang Jianghe, who was anxious, did not know that Tang Cheng's move was intentional, because he was worried that if he helped Zhang Jianghe find the correct answer at once, he would arouse Zhang Jianghe's suspicion later.
After several experiments that were destined to fail, Tang Cheng, who seemed to have an epiphany, slapped his forehead and then copied the marked content again. "Uncle, look, we have marked half of the original 450 words. Now I rearrange them according to their original order, with fifteen words in each row, and then use the most commonly used approximate value of pi, 3.14 , re-annotated from this new content.”
Tang Cheng used pi for the second time to mark the content from the new content. He did not continue to use calipers, but directly followed the rule of three, one, and four to select five characters from the fifteen characters in the first row. Zhang Jianghe looked at the five words copied by Tang Cheng on another piece of paper, and couldn't help but feel a burst of ecstasy in his eyes. It turned out that Tang Cheng's method worked, because a name appeared among those five words.
